I'd read something ages and ages ago (when the 486SX first came out in fact) that the speed difference between the 836 and 486 would actually take place if you were using 32 bit software, eg. OS/2 and various Unices. Running DOS and Win- dows apps the 386 of the same clock speed would be a little slower but not by much. So a 386/40 could well be faster than a 486DX/25 or 486SX/25. Depends on the code you run. Experience shows this to be the case. My 386/40 runs rings around the older 486 machines around here. Now it is true one can stick an Overdrive chip in a 486SX machine, but what do they cost? Also if you have a DX ma- chine you can't just go out and buy a DX2/50 either. Intel won't sell them to individuals. -- ------------------------------------------------------------------------------- Iskandar Taib | The only thing worse than Peach ala Internet: NTAIB@SILVER.UCS.INDIANA.EDU | Frog is Frog ala Peach Bitnet: NTAIB@IUBACS !
